Workshop: Catch Shared-Host Drift With a Five-Probe Floor Card in 85 Minutes
16+ hour, 32+ min ago (594+ words) Measurement talk in developer circles often outruns the tests that still discriminate. When a host starts returning fluent prose, empty objects, or a constant label, yesterday's demo stops being evidence. A floor card is deliberately small so a classroom can…...

The Database I Deleted: Migrating an Agentic RAG App to AWS Serverless #3
1+ day, 8+ hour ago (901+ words) Re-deriving the corpus surfaced two problems that had nothing to do with AWS. RRF dedupes by doc_id. So 303 chunks were silently shadowing each other during fusion — one of each pair could never surface, and which one survived depended on iteration order....
AWS tells you something changed. Figuring out what actually happened is another story.
2+ day, 5+ hour ago (199+ words) I kept running into the same problem with AWS. The alert usually isn’t the hard part. The investigation is. An IAM policy changes, a security group gets opened, or a role suddenly has permissions it didn’t have before. AWS gives…...
Reviewing Generated Terraform: The Destroy Count, count vs for_each, and a Comment in the Wrong Place
3+ day, 23+ hour ago (515+ words) Terraform is the worst place to accept generated code uncritically, because it is the one where "wrong" can mean a deleted database rather than a failing test. It is also a place where Copilot is genuinely useful — provider schemas are…...
